I've compiled a few references below. The workflow comes down to using Lathes to sketch out the body parts one by one, then use "Weld" to join the parts into a single skin ready for sculpting with the sculpt tools.

In practice a lot comes down to your reference photos/sketches. Also it is a lot simpler to make a symmetrical pose as you can mirror the model and limbs. For a posed character the first step of drawing Lathes takes a bit longer, and you have to sculpt both sides of the model independently.

I recommend modelling the head, and perhaps hands, as separate models. It is much easier to work on them separately (especially using mirroring on the head)
